It should be noted that this A1660 iPhone 7 model supports FDD-LTE bands 1, 2, 3, 4, 5, 7, 8, 12, 13, 17, 18, 19, 20, 25, 26, 27, 28, 29, and 30, along with TD-LTE bands 38, 39, 40, and 41. It is designed for Verizon, Sprint, and numerous smaller US carriers (excluding AT&T or T-Mobile), as well as for China Mobile, China Telecom, and China Unicom in mainland China, and 3, China Mobile HK, CSL, and SmarTone in Hong Kong.

All iPhone 7 models, regardless of carrier, feature a 4.7-inch widescreen multitouch LED-backlit 1334x750 "Retina HD" display (326 ppi, 625 cd/m2) and a solid-state, taptic-engine-powered "clickless" Home button. It includes a rear 12-megapixel camera with optical image stabilization, an f/1.8 aperture, a six-element lens, and wide color capture, plus a front 7-megapixel "FaceTime HD" camera that supports 1080p video.

The iPhone 7 has an aluminum body and is rated IP67 for splash, water, and dust resistance (not waterproof). It features stereo speakers and a Lightning port but omits a traditional headphone jack. Initially, it came in five colors: "silver," "gold," "rose gold," "black" (matte), and "jet black" (glossy), with Apple noting the jet black finish could show micro-abrasions. A (PRODUCT) RED Special Edition was available from March 21 to September 12, 2017.

Internally, the iPhone 7 is powered by a 64-bit quad-core "Apple A10 Fusion" processor (two high-performance, two high-efficiency cores), 2 GB of RAM, and 32 GB, 128 GB, or 256 GB of storage. (Jet black and red were initially 128/256 GB only; a 32 GB jet black model was added and the 256 GB option was discontinued for all colors on Sept 12, 2017). It also supports 802.11ac Wi-Fi with MIMO, Bluetooth 4.2, LTE (4G), and NFC for Apple Pay.

Apple estimates the iPhone 7 delivers up to 40 hours of audio, 14 hours of 3G talk time, 12 hours of 3G/LTE internet use, 14 hours of Wi-Fi internet use, 13 hours of wireless video, and 10 days of standby.

In the US, this iPhone 7 was initially sold unlocked but subsidized on a two-year Verizon or Sprint contract for US$199 (32 GB), US$299 (128 GB), or US$399 (256 GB). Unlocked and contract-free, it was originally US$649, US$749, or US$849. It was also available through leasing and installment plans like the "iPhone Upgrade Program" and "Apple iPhone Installments."

Technology analysts extensively praised this versatile iPhone 7 variant for its exceptional carrier flexibility, supporting both CDMA and GSM networks across diverse markets from Verizon and Sprint in the United States to major carriers throughout China and Hong Kong. Professional reviews highlighted how this model's comprehensive band support represented Apple's most ambitious attempt at creating a truly universal smartphone, capable of seamless operation across traditionally incompatible network technologies. Critics particularly commended the device's ability to deliver consistent A10 Fusion performance and camera quality regardless of network type, eliminating the traditional compromises associated with multi-carrier compatibility. Industry specialists recognized this implementation as a significant engineering achievement that showcased Apple's dedication to providing unified user experiences across fragmented global telecommunications infrastructures.
